Siemens-Telecontrol: Connecting industrial outstations inexpensively and securely
To improve availability, the CP 1243-8 IRC offers the option of establishing an additional connection via the second WAN interface (for route redundancy). For this, a so-called teleservice (TS) module – for instance, an RS 232 serial interface or dial-up modem (analog, ISDN, and GSM) – is connected to the second WAN interface. Users can operate with one or the other interface, or both simultaneously. Comprehensive diagnostic options – either locally via error messages by LED display, in the Simatic Step 7 engineering tool, or through a web server – offer fast and highly informative analyses of the station status. This enables users to quickly and easily configure connections to new modules with data-point configuration in Step 7. In the Step 7 Professional engineering software in the TIA portal, the user simply selects the data to be transferred from the Simatic S7-1200 CPU and specifies the desired communication parameters.
In addition, the new
communication processor is equipped with comprehensive security features
such as firewall (stateful inspection) and VPN protocol.
